It is of course ok as others have stated, but although I have not used S a lot, in general overtaking, personally the few times I have it has annoyed me, I much prefer to use the paddles to put me in the gear I want to be in ready to over take, the only problem with this is after a while it automatically goes back into D again, this also annoys me, but I can see the logic in this, as you would sometimes forget what gear you were in and stay in that gear burning loads of juice. but the few times I have used S i have it ready in a gear to over take in S mode, and as soon as I floor it it changes down, revs the hell out of the engine and then needs to change back up, where as using the paddles, (M mode) can hold you at the right revs in the right gear thus put your foot down and she flies
